Preheat oven to 400°F. Cut apples into thin slices, place in large mixing bowl.
Combine sugars, cinnamon, flour, nutmeg, and salt; mix thoroughly. Sprinkle over the apples and stir until
coated.
Use one of the pie crusts to line the bottom of 9" deep dish pie pan. Brush this bottom crust with beaten egg white.
Add apple mixture and dot evenly with butter. Lay second pie crust over the top of the apples, gently pressing down. Cut slits to release steam while
cooking. Brush top crust with remaining egg white – sprinkle with white sugar.
Bake pie in preheated oven 50 minutes, or until golden brown. Check after 30 minutes, and if the crust is already browned reduce heat to 350°F.
